Abstract
A stent including a helical mesh coil is provided having a substantially rectangular cross-section and a band width equal to at least one-quarter to one-third of the maximum expanded circumference of the stent. The helical mesh has a multiplicity of openings forming a lattice that preferably provides about 60% open space or more. Alternative embodiments of the stent include free ends that preferentially overlap neighboring turns of the coil, and integrally formed barbs that enhance resistance to localized compressive forces. Methods of deploying the helical mesh coil stent also provided.
